X Mod 0
This instruction was updated to conform to IEC 61131-3 ed. 2 table 28 for
MOD function. In this case, anything Mod 0 results in 0.
This implementation affects the MOD instruction.

AND, NOT, OR, and XOR Support for REAL

The verification rules for these instructions now let you use REAL operands in
RLL routines that are based on existing behavior in non-RLL languages.
This implementation helps to make programming for these instructions
consistent across all languages.
Also supported in RLL.
